NR Uplink Priority Handling for Positioning SRS Resource Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) communication systems, there is no solution for channel/signal transmission when Sounding Reference Signals (SRS) used for positioning conflict with resources of Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH).
Innovation Solution
A method and device that prioritize and transmit channels/signals based on a defined priority relationship, where channels/signals with high priority are transmitted and those with low priority are discarded, specifically for SRS used for positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SRS used for positioning transmits in conflict with PUSCH and PUCCH resources, then positioning function can be maintained, but channel transmission reliability deteriorates due to no resolution mechanism
Solution Approach 1:
The patent introduces priority parameters (first priority and second priority) for SRS to resolve resource conflicts. By changing the parameter structure to include priority levels, the system can determine transmission behavior when SRS conflicts with PUSCH or PUCCH, thereby improving both reliability and adaptability.
Solution Approach 2:
The patent makes the transmission behavior dynamic by allowing the terminal to determine whether to transmit SRS based on priority comparison with PUSCH and PUCCH. This dynamic decision-making capability enables the system to adapt to different resource allocation scenarios while maintaining reliable transmission of high-priority channels.
2Reliability
If priority-based transmission resolution is implemented, then channel transmission reliability improves, but device complexity increases due to priority determination and comparison mechanisms
Solution Approach 1:
The patent simplifies complexity by using clear parameter definitions (first priority for SRS, second priority for PUSCH/PUCCH) rather than complex decision algorithms. The terminal only needs to compare these predefined priority parameters to determine transmission behavior, making the mechanism straightforward despite the added functionality.

AI summary
A transmission method and a device are provided. The method includes: in a case that resources of at least two of channels or signals at least two of channels or signals conflict, transmitting a channel/signal with a high priority, and/or discarding a channel/signal with a low priority based on a priority relationship between the at least two of channels or signals, where at least one of the at least two of channels or signals is: a first SRS, where the first SRS is an SRS used for positioning.
